Laser-based device uses light scattering method for precise detection of environmental contaminant particles

Honeywell's HPM series particle sensor, available now from TTI Europe, is designed to work in HVAC systems and consumer products such air purifiers to measure air quality in homes, buildings and public spaces. The sensor uses laser technology to accurately and cost-effectively monitor for fine inhalable particles that are 2.5 micrometers in diameter or smaller. For reference, the average human hair is nearly 30 times larger at 70 micrometers in diameter. The laser-based sensor uses a light-scattering method to accurately detect and count particles in the concentration range of 0 micrograms-per-cubic-meter-of-air (µg/m3) to 1,000µg/m3 in a given environment. The sensor then analyzes the particulate size and concentration in real time to enable systems to provide alerts and allow operators to take remediation actions. With its heavy industrial level electromagnetic compatibility, the sensor performs accurately in harsh, challenging environments. Building operators benefit from the sensor's industry-leading long life of 20,000 hours, which allows for stable operations and continuous use. The new sensor can be used in a range of consumer products such as air purifiers, automotive air systems and mobile air quality detectors.
